-T0 all it majy concern:

Be it known that I, EDWIN A; YOUNG, a citizen of, the United States, residing at Mitchell, .in the county of Davis'on and State P PGHing vessels. I i

-' Objects of the invention are to so con-- struct and arrangethe paddles or floats that they will enter and leave the water edgewise, and thereby avoid loss of power; to provide means for causing the paddlesto-be, heldin working position during the proper periods a of their revolutions and means for tripping them to permit them" to feather at the proper "times, and generally to improve and simplify go the construction and operation of the propelling mechanism, to the end of saving power Q and increasing the speed of the Vessel. 'The improvements for accomplishing these objects are illustrated in the accompanying draw I. in s, in which- J I igure 1'is a plan view of aJpaddle-wheel 1 provided with my improvements. Fig. 2 is a transverse sectionalelevation on the broken Y line a w of Fig. 1, viewed from the'right, and

ends of-the'paddles are socketed or to which theymay be fastened in any other way: On the middle of the shaft is a similar hub or collar 7, to which are fastened the radial hich the radial arms 6 for supporting the be i arms8 for carrying the'supports and circular guides forthe middle portionsiof the paddles.

"The arms 6 on the respective hubs 5 maybe connected by tie-rods!) and withthe arms 8 by the longitudinal rods 10.

On the ends 'of the paddles 'arebolted or-'5 otherwise secured castings. 11, provided' with outwardly extending spindles... 12, arranged in line with the axes of the paddles, and these spindles arejournaled in bearings 13 formed at the extremities of the arms 6,: so thatthe paddles normally are free to rotate on their end bearings.

The middle supports consist oflrin s circular'guides 14,-attached to the en sof the in its guide-ring antifriction-rollers 15. These guide rin s serve tosu port the middleportions of t e paddles, w 'lethe rollerspermitt arms 8,. and encircling the paddles. Eaclrf paddle has secured'on its opposite sides.with-' the paddlesto turnfreely within the rin s.;* i

.The rings are conneoted to one another y tie-rods 16. I a

On the outer edge of one en d (the l'eft-h'and end, as shown in Fig. '1) of'each ipaddle-is atfriction-roller 18. A plate or frame 1 secured to the beams or. framework 1, is protached a bar 17, which extendsbeyond the I r I paddle and carries at its extremityanantivided with a fixed guideway 19 of somewhat these rollers are upper. and lower movable ovalshape, slightlypoint'edtoward the lower [end to serve as the innerguide'for the rollers 18. At the outside ofthis path of travel of connected; to intermedlatefixed guide-sec- I tions 22. The upper'members'20 are pivot -ed", as 'at'23, and have counterwei hts 24,

-which cause them to gravitate 'to c ose the pathway, as indicated in Fig. 4 or at thel'left in Fig. 2, and an ascending paddle-roller" 18 Y moves thej'guide '20 outward to clear the I pathway, as indicated at the rightin The lower members 21 are pivoted,' as*'at25, to the part 22 and gravitate of 'theirfjown 'weight to contact with' stop's 26' to keep the lower pathway normally op'engas shownm Fig. 2. These guides may be adjusted by pivoting them in any of the holes 27 shown in the part 22. At the other' ends of thepaddles (the right in Fig. 1) the spindles 12 ex- IOO tend beyond the arms 6 and have rigidly secured to them wipers or tripping-arms 28, and on the frame 1 at that end of the wheel are two pendent catches or trips 29 for engaging the wipers 28'. The trips 29 are pivoted at 30 to swing freely, but adjustable stops 31 are so placed on the frame as to prevent outward swinging movement beyond practically vertical position, and theyare weighted by inward arms 32, adapted to hold them normally in position against the stops. On the lower ends of the trips are rollers 33, against which the wipers 28 contact in their movements.

In operation when the wheel is revolved in the direction indicated by the arrows the rollers 18 of the descending paddles will ride successively on the outer surfaces of the guides 19, 20, 22, and 21, thereby presenting each succeeding paddle edgewise as it enters-the water, turning it gradually asit descends, and holding it substantially flatwise during its lower movement and until it reaches the point of beginning its ascent. In this movement the wiper 28 will engage the left-hand trip 29 and without resistance swing it inward from the position shown by full lines to that shown by dotted lines in Fig. 3; but when the wiper contacts with the second trip the stop 31 will prevent the trip from swinging and the movement of the wiper over the face of the trip-roller 33 will serve to swing the wiper, and thereby turn its axis andv the paddle to which it is fast. This latter movement results in so turning the paddle as to bring its guide-roller 18 in position to enter the open way between the guide members 19 and 21, and the further revolution of the wheel will cause the contact of the guide-roller with the outer guides to turn the paddle substantially edgewise as it ascends. If the direction of revolution of the wheel is reversed, the mode of operation of the devices will be the same as that described.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a feathering paddle-wheel, the combination with a shaft and a series of axiallypivoted paddles revolved thereby, of guiding devices for'controlling the feathering movements of the paddles in their descent, tripping devices for starting the feathering movements for the ascent and guiding devices for directing the further edgewise movements of the paddles, substantially as set forth.

2. Ina feathering paddle-wheel, the combination witha shaft and a series of axiallypivoted addles revolved thereby, of guidin devices or causing the paddles to enter and rise from the water edgewise and for turning them fiatwise and so maintaining them during their working movements, and tripping devices for returning them to edgewise position at the end of their working movements, substantially as set forth.

3. In a feathering paddle-wheel, the combination with a shaft and a series of axiallypivoted paddles revolved thereby, of guiderollers and wipers carried by the paddles, guides with which the rollers en age to cause the paddles to enter the water edgewise, turn to flatwise working positions and emerge edgewise, and a trip with which the wipers engage to turn the paddles from fiatwise positions at the end of their working movements, substantially as set forth.

4. In a feathering paddle-wheel, the combination with a shaft and a series of axiallypivoted paddles revolved thereby, of guiderollers on the outer edges of the paddles at one end of the wheel and wipers on the axes of the paddles at the other end of the wheel, guides with which the rollers engage to cause the paddles to enter the water edgewise, turn to flatwise working positions and. emerge edgewise, and a trip with which the wipers engage to turn the paddles from flatwise positions at the end of their working movements, substantially as set forth.

5. In a feathering paddle-wheel, the combination with a shaft and a series of axially-pivoted paddles revolved thereby,of guide-rollers on the outer edges of the paddles at one end of the wheel and wipers on the axes of the paddles at the other end of the wheel, a fixed oval-shaped guide and at its op )osite sides upper and lower gravitating gul e members with which the rollers successively engage to cause the paddles to enter the water edgewise, turn to flatwise working positions and emerge edgewise, and a trip with which the wipers engage to turn the paddles from flatwise positions at the end of their working movements, substantially as set forth.

6. In afeathering paddle-wheel, the combination with a shaft and a series of axiallv-pivoted paddles revolved thereby, of radial arms providing bearings for the paddle-axes, supports for intermediate portions of the paddles consisting of guide-rings within which the paddles turn on roller-bearings, and radial arms connected to the shaft for carrying the guide-rings, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of August, 1905.
